CORNIGE-MOLDl Specification of Letters'Patent. Patented lflayll, 1918.

Application filed March 9, 1917. Serial No. 153 675.

To aZZ 107mm it may concern:

Be it known that I, PAoLo Znrrrrn, a subject of the King of Italy, residmg at New York city, in thecount'y of'New York and v State'of New York, have invented new and useful Improvements in Cornice-Molds, of which the following is a specification.

This invention relates to masonry and concrete structures," and more especially to implements employed in finishing the plastering with a cornice inthe angle between the wall and ceiling; and the object of-the same is toproduce a hand tool in the form of a. running mold. I

The invention consists in the details of construction applied" to a mold of this charaoter so that it will close any miter, whatever the configuratio'n or design of the cornice, and so that it will finish either an inneror'an outer angle. thereof.

Details of'construction are set forth in the following specification, and "reference is made to the accompanying drawings where- Figure l .is a sectional view through one side wall and its cornice and the-ceiling, an elevation of the cornice on the next side wall at right angles theretofand an elevation ofthe tool use.

Figs. Q'and 3 areviews of the right and left tool's viewed as they appear when looking from above, and with a hand in outline applied to the left tool.

Fig, 4% is a" similar view of a slightly modified form of the right tool.

I In the drawings I have used the letter W to. designate'awall, and O is the ceiling meeting the same at the angle A." In this angle is often formeda cornice consisting of an upright leaf U against'the wall and a .horizontahleaf 'H beneath the ceiling, and

the exposed faces of'these leaves may have any suitable design or configuration. The present invention is a tool or implement known as a running mold by means of which the plasterer may give to the faces of both leaves of the cornice the desired configuration clear up into the angle at the corner of the room. It is to be understood that the cornice which is usually made of plaster ofParis or like plastic substance such as Kingston'e' or "the like, is applied to the wall and to the ceili'n rather roughly at first, and'the outline of its originalface is indicated at X in Fig. 1; and it is the object of this invention to provide a tool in the shape of a running mold by means of which the design configuration can be given to this cornice by shaping it or planing off the surplus material as it were.

Coming now to the details of construction and referring to the same by reference numerals, the frame of this tool which ispref erably of wood or other light material comprises a slipper l which stands ina horizontal plane when the mold is being used, a blade 2iwhich stands in a vertical plane when the mold is in use and whose lower edge is attached to the upper face, of the slipperby any suitable means, as by being set into a recess 3 therein and firmly secured in said recess, and a handle 4: above the slip per and behind the blade and firmly con-- plet 6 whose working edge. 7 projects beyond the corresponding edge of the blade and is given a 'co'nfiguration which will impart the proper design .to the upright and horizontal leaves of the cornice when their faces are finally reduced to their finished condition. I desire it understood that any design of cornice may be made with this tool, whether the faces of its leaves are more or less elaborate than as shown in the drawings and'whether they are wider or narrower; 'For thispurpose it may be desirable to have the templet removably attached to't-he blade, so that the one illustrated herewith can be taken off and anothersupplied having. a different configuration on its working edge 7 but more probably "anothe rpair of'tools will be used in that case, 'so that the necessity for removing the templet will be obviated. As seen in Figs. 2 and 3 the tool is made in twomemhers, the former being a right'hand member and the latter a lefthand member, and when -working into a right-angular corner the blade and templet of eachmember is set at strictly forty-five degrees to the outer edge 8 of the slipper which travels along the wall below the cornice and against the face of the finished plaster. For the purpose of keeping the slipper always parallel with the wall W, its edge 8 may be provided with a plurality of wear faces or shoes 9, or a single shoe may be attached thereto and continued throughout the full length of the edge 8. correspondingly the upper edge of the blade 2 at its rear 0r heel end may carry a wear plate or shoe 10. When the latter travels in contact with the face of the plastering on the ceiling, while the shoes or shoe on the outer edge 8 of the slipper travels in contact with the face of the plastering on the wall, the entire mold is held and maintained in'proper position with respect to the cornice so that when it is advanced along the line indicated by the arrow, the proper design configuration is given to the upright and horizontal leaves of the cornice as shown.

In the use of this tool or mold, the cornice is of course at first in its unfinished condition as indicated by the line X. When theright hand tool shown in Figs. 1 and 2 is applied and moved to the left as indicated by the arrow in Fig. l, theworlring edge 7 of its templet 6 outs away or plows ofi the excess material from the line X down to the line of the face of the finished leaves of the cornice, and this excess material, being forward of the templet and the blade, drops from the tool onto the hawk (not shown) and which is usually carried in the other hand of the workman at the same time. Such would be the result with the tool shown in Fig. l. 1 preferably extend the base plate or slipper, however, as seen in the remaining views, so as to form a small shelf 11 beyond the active face of the templet and below the line of the upright leaf U of the cornice, taking care to cut away the forward end of the shelf at 12 so that it shall not extend to the front end of the blade and templet at the point 13, and thereby leaving a space over which the surplus material may fall onto the hawk referred to. in the first passage of this tool along the line indicated by the arrow, much surplus material will be removed and doubtless it will accumulate upon the shelf 11 and run 0d the same onto the hawk; but in subsequent passages of the tool, after the surface of the cornice has been carefully moistened or wetted as usual when it is nearing completion, but little if any surplus will be shaved or planed on", as it were, and this will fall upon the shelf which meanwhile has been relieved of what formerly accumulated there. Thus the shelf is utilized as it were to catch the drippings, and the operator at this time may have his a other hand free because there is no necessity of now, carrying the hawlr. The advantage of the shelf is now apparent, because invariably the tendency of the artisan at the last moment when his cornice is being finished is to use both hands to hold the tool closely up in the corner and perfect his job while the plaster is yet in condition to he worked. llloreover, either he or his mate must work with the other tool along the adjacent wall and up into the same corner, and it would not be desirable to have the shelf extend completely to the point 13 because when the latter strikes the corner the shelf will not strike the plastering and certainly should not strike the upright leaf of the other cornice. Finally, the space left by shortening the shelf gives the artisan a chance to pass hisfingers around the front end of the tool, and I may even cut away the corner of the shelf as indicated'at 15 to give a place or rest for the thumb.

The use of the left hand tool shown in Fig. 3 is the same, excepting that of course it will form the cornice along the wall at the left side of Fig. 1 instead of that in the background thereof as indicated. Thus by the use of a pair of complementary or companion tools as'shown in Figs. 2 and 3,110 matter what the shape of the working edge 7 thereof, this invention may be applied to any mold that closes a miter at the corner as described. While I have shown the blade and templet standing across a the slipper at strictly forty-five degrees, which will be their position when the walls at the corner of the room make a right angle, it will be clear that by setting these elements at different angles to the slipper miters of other angles might be closed in corners which are either obtuse or acute, but this need not be elaborated in the drawings or description. Yet I do not wish to be limitedto the size or shape of parts, and have described wood as used only by preference because it is light.

What I claim as new is 1. The herein described running mold, the same comprising a slipper having across its upper face an oblique recess extending to its corner, shoes along the active edgeyof said slipper, an upright blade whose lower edge is secured in said recess and extends to the corner of the slipper and whose front and upper edges are cut out roughly to conform with the configuration of the cornice to be produced, the rear extremity of its upper edge being carried upward into a heel, a shoe thereon, a templet removably secured to the 7 front face of said blade with its working edge projecting beyond the edge of the blade and its front end coincident with the corner of the slipper, the latter projecting beyond said templet to produce ashelf torminatingshort of the front end of thetemplot, and a handle connecting the blade and slipper.
